Wireless charging technology Radio transmission technology can be divided into small power wireless charging and high power wireless charging.

Small power wireless charging is often used by electromagnetic induction, such as the Qi mode of charging the mobile phone, but the wireless charging mode of zte's electric vehicle adopts the inductive type. High power wireless charging often USES resonant (most of the electric vehicle charging) this way by the power supply equipment (charger) to transfer energy to the utilization device, the device using the received energy of the battery, and at the same time for its own operation.

Because of the magnetic transmission of energy between the charger and the electrical device, there is no wire connection between the two, so both the charger and the electrical device can be exposed without conducting contact.
